To (r53 whom is may concern:

Be ii; known that LTNILLIF; K: Hose-crew, a citizen or" the. Uni edStores, and a resideni; of Taunlcon,- in the county of Brisiol and fiters of Massachusetts, have invented an. improvement in Sheet-Piling liiecbanism for Frintiriglresses, of which the iollowing descripiion inconnection with illfifi so compenying drawinggis a specificeiiou, likecharacters on the drawings repr se-erasing l ke This einvention relatesthe mechanism for printing presses le-rly 'lomeans to preveni freshlyshe ts from offsetting. 4

have shown my invention applied ;sisndcrd two revolution ed andcylinrinizingprcss, but I desire i". to be on cod "chill; the inventioninc desired fiype of primer pro v livery of the fly type or a pri sudpartied and lare enfollowing" mechanism: .l c guseous marker.Preferably, however,

any kind of delivery, as, for example, a de nted side up delivery. YReferring more particularly to the drawings, I have herein. representeda press of the fly type of delivery, the fly being represented at 1 andbeing adapted to receive the printed sheets in any suitable manner fromthe printing mechanism proper.

Iprei'crably provide a sheet piling box to' receive the sheets from thefly 1.' I have herein. represented the piling box as having a fixed side2 suitably connected as indicaied l; 3'3 to the side frames 4 of thepress and an adjustable side 5, the ends Whore-f are secured by screws 6adjustable along longie tudinel slots? in the said side frames, thuspermitting. she side &0 be adjusted toward and from the side 2 toaccommodate difi'erout; sized sheets. The sides 2 and 5 are notched asiudicar/edat 8 to receive adjustable ends 9 't-lulis permittingtransverse adjustrneni of the sides of the box. vThe sides and ends ofthe box should be so positioned and adjusizec-as to sm'round andsubsterr ciully fiiilie sheets-piled ,therein, thus preveniing the fromfreely escaping between the last few sheets, and thereby flout-c ing' orseparating the sheets inia measure sud giving the ink thereon anopportunity to dry before she weight of the accumulating slicers issuilicicnl; so expel all of and rho cause offsetting to occur.

lpreferably provide a vertically movable bottom or piling board 10,which issupplied with supporting means (not shown) whereby it forms thebottomof the piling box when in its upper position and can be graduall'y lowered as the pile accumulates and is finally landed on a truck.Any suitable or usual means co-acting with the piling board 10 maybeemployed.

the air While 1 may employ any suitable means foo introduce air betweenthe sheets as they are being piled, Ipreferebly provide the v provide asuitable blower 11 driven by belt 12 frame pulley 13 upon shaft 14 andwhich may be any suitable she-fl:v of the printing mechanism, or ifdesired the blower may be driven fromsome external source of power. Fromthe blower extends a, pipe 15 herein represented as having an up endingportion 16 ex'tending'to the plane or the piling box and a horizontal;

piled sheets having means temporarily to confine the entrained airbeneath a sheet as itis-received by the receiver, and co-acting ,meansto discharge a jet of air wholly beneath the said sheet while it isbeing so received.
